Liquid spraying device used for spraying liquid medicine to asthma patient, has particle classifier that enables collision of liquid medicine during discharge operation so that micro-mist droplets are sprayed in discharge direction

摘要

The device has container (1) that is provided with receiving chamber (10) for containing liquid medicine. A discharge opening (12) is provided in container for discharging the liquid medicine. A spray module (2) is connected to driving source (4) so that liquid medicine collides with discharge as result of vibration of spray module. The spray module sprays out fog droplets, and particle classifier (3) is separated from the spray module to enable collision of liquid medicine during the discharge operation so that micro-mist droplets are sprayed in discharge direction.
